WebJan 27, 2016 · 1 Answer. Sorted by: 0. Noting that u and v are both unit vectors, i.e. ‖u‖ = ‖v‖ = 1, we can then state that: ‖u + v‖2 = (u + v) ⋅ (u + v) = u ⋅ u + v ⋅ v + 2(u ⋅ v) = ‖u‖2 + ‖v‖2 + 2(u ⋅ v) (3 2)2 = 1 + 1 + 2(u ⋅ v) ∴ u ⋅ v = 1 8. Then, by applying similar reasoning, you can derive the value of ‖u − v‖.

Web1. The norm (or "length") of a vector is the square root of the inner product of the vector with itself. 2. The inner product of two orthogonal vectors is 0. 3. And the cos of the angle between two vectors is the inner product of those vectors divided by the norms of those two vectors. Hope that helps! WebGiven the vectors v = h1,2,3i and w = h−2,3,1i, compute both w × v and v × w. Solution: We need to compute the following determinant: w × v = 1 i j k w w 2 w 3 v 1 v 2 v 3 = ... that is, u · (v × w) = −24. We conclude that V = 24.
